lmtsh complains about lack of Lua support

g0xA52A2A commented 6 years ago

I have the following installed.

$ rpm -qa | grep lua
lua-5.1.4-14.el7.x86_64
lua-devel-5.1.4-14.el7.x86_64

In the config.log of the LMT build I have the following, abbreviated to what I believe to be the relevant pieces of information but I can provide the full log if required.

I have set up the database per the wiki and am able to list it.

$ /usr/sbin/lmtinit -l -u lwatchadmin -P

However I am unable to use lmtsh

$ /sbin/lmtsh -v -d
/etc/lmt/lmt.conf: LMT was built without LUA support
[LMT:init] Missing configuration file or configuration info: /etc/lmt/lmt.conf

The file /etc/lmt/lmt.conf does exist and contains the correct information.

I don't see the issue yet. Some notes so far below.

OP didn't specify an LMT version but at the time the issue was created, the most recent release was 3.2.3.

I haven't found a reason it would be, yet, but I wonder if this is a side-affect of https://github.com/LLNL/lmt/issues/44.

Messages:

/etc/lmt/lmt.conf: LMT was built without LUA support

This appears to be emitted only by liblmt/lmtconf.c:247 lmt_conf_init(), and only if HAVE_LUA_H is not defined.

[LMT:init] Missing configuration file or configuration info: /etc/lmt/lmt.conf

$cf is "/etc/lmt/lmt.conf" based on the error message. This implies ${prefix} is empty (""). This message comes from scripts/LMT.pm.in:63 when _parseConf($cf) returns an empty hash. _parseConf() is defined at LMT.pm.in:835. _parseConf() runs "lmtinit -x -c $cf" and parses its output to populate the hash. The command must have had no output at all, or failed to run entirely.

And the first thing that lmtinit does after parsing options is call lmt_conf_init() which would be expected to fail with the error message above. So the two error messages are due to the same root cause.

This was a while ago but I got LMT running though I can't recall what steps I took. I have no longer work on this system so I can't check unfortunately, feel free to close this issue.

OK. I don't see how to reproduce your symptoms, so closing. Thanks.
